Water may drip from the safety valve’s
overflow pipe. The entire length of the over-
flow water pipe must be routed to a suitable
drain and be inclined to prevent water pock-
ets, and must also be frost-proof. The over-
flow pipe must be at least the same size as
the safety valve. The overflow pipe must be
visible and its mouth must be open and not
located close to electrical components.
The safety valves must be actuated regularly
to remove dirt and to check that they are not
blocked.

Maintenance
SAFETY VALVE (NOT ENCLOSED)
You can find the safety valve on the incoming pipe (cold
water) to VPB S/ VPBS S.
The water heater’s safety valve sometimes releases a
little water after hot water usage. This is because the
cold water, which enters the water heater to replace
the hot water, expands when heated causing the pres-
sure to rise and the safety valve to open.
The function of the safety valve must be checked regu-
larly. Perform checks as follows:
1. Open the valve.
2. Check that water is flowing through it.
3. Close the valve.
NOTE
If this pressurised water heater develops a
fault, e.g. a flow of hot water from the overflow
pipe, turn the heat pump off and contact your
installer.
NOTE
Do not remove or adjust any components that
are part of this pressurised water heater. Con-
tact your installer!
TIP
The safety valve is not delivered with
VPB S/ VPBS S. Contact your installer if you
are unsure how to check it.
EMPTYING

Pipe installation
GENERAL
NOTE
Pipe installation must be carried out in accord-
ance with current norms and directives
An internal support bush must be fitted when a plastic
or annealed copper pipe is used.
Water may drip from the safety valve’s overflow pipe.
The entire length of the overflow water pipe must be
routed to a suitable drain and be inclined to prevent
water pockets, and must also be frost-proof. The over-
flow pipe must be at least the same size as the safety
valve. The overflow pipe must be visible and its mouth
must be open and not located close to electrical com-
ponents.
Caution
Ensure that incoming water is clean. When
using a private well, it may be necessary to
supplement with an extra water filter.
SYSTEM DIAGRAM
VPB S/ VPBS S is a series of water heaters that are
suitable for connection to e.g. a heat pump.
VPB S/ VPBS S consists of a hot water tank with internal
anti-corrosion protection made of copper, stainless steel
or enamel, as well as a charge coil
The charge coil heats the domestic water, resulting in
excellent properties for hot water charging.
VPBS S300 has an additional coil, which is used for an
external heat source, e.g. thermal solar panels or a stove
with a back boiler.

trated.
• Install the safety valve as illustrated. Recommended
opening pressure is 0.25 MPa (2.5 bar). For information
about max opening pressure, see technical specifica-
tions.

CONNECTING COLD AND HOT WATER
The settings for hot water are made in the compatible
product’s menu system.
Install as follows:
• controlling hot water sensor (BT6) (placed in the
middle of the water heater)
• vacuum valve (FL6) (vacuum valves only apply to
copper)
• shut-off valve
• non-return valve
• pressure relief valve
The safety valve must have a maximum 1.0 MPa (10.0
bar) opening pressure and be installed on the incoming
domestic water line as shown.
• mixing valve
A mixer valve must also be installed, if the factory
setting for hot water is changed. National regulations
must be observed.

INSTALLATION ALTERNATIVE
NOTE
This is the outline diagram. Actual installations
must be planned according to applicable
standards.
VPB S/ VPBS S can be installed in several different ways,
some of which are shown here.
Further option information is available at nibe.eu/ODM
and in the respective assembly instructions for the heat
sources used.
To external heat source
VPBS S300 can be docked to an external heat source,
e.g. a stove with a back boiler or a thermal solar install-
ation.
Install as follows:
• sensor for external heat source, tank (BT54)
• pressure gauge
• expansion vessel
• pressure relief valve
• AXC module
• circulation pump
• sensor, external heat source (BT53)
P

XL13
Connecting hot water circulation (VVC)
VPB S/ VPBS S stainless steel and enamel have a con-
nection that allows hot water circulation, the HWC return
is connected to this (XL5).
Hot water circulation
A circulation pump can be controlled by a ground-source
heat pump or exhaust air heat pump, indoor module or
control module for circulation of the hot water. The cir-
culating water must have a temperature that prevents
bacterial growth and scalding, and national standards
must be met.

Electrical installation
GENERAL
Electrical installation and wiring must be carried out in
accordance with national provisions.
NOTE
Electrical installation and any servicing must
be carried out under the supervision of a quali-
fied electrician. Disconnect the current using
the circuit breaker before carrying out any ser-
vicing.
SENSORS
VPB S200 and VPB S300 can be supplemented with up
to two hot water sensors, one for display and one for
control. The displaying sensor (BT7) is fitted at the fact-
ory and placed in a submerged tube (UA1), the con-
trolling hot water sensor (BT6) is placed in the sub-
merged tube for control sensor (UA2). In cases where
it is only possible to connect one sensor, use the sub-
merged tube for the controlling sensor (UA2).
VPBS S300 can also be supplemented with a sensor for
an external heat source (BT54). This is placed in the
submerged tube for the external heat source (UA3).
Use the sensors provided with the heat pump (or other
heat source). When no heat sensors have been provided
these must be ordered from the manufacturer of the
heat source.
The figure shows VPBS S300.

DIRECT-CURRENT ANODE
VPB S/ VPBS S Enamel is equipped with direct-current
anode and enclosed with potentiostat from the factory.
The anode cable (W1) is installed in the anode from the
factory and only needs to be connected to the potentio-
stat.
1. Route the anode cable (W1) along the docking pipe,
supply line (XL8).
2. Connect the anode cable (W1) to the potentiostat.
3. Connect the potentiostat to a suitable 230 V wall
socket.
NOTE
The cable between the potentiostat and the
anode must either be extended or shortened.

FILLING AND VENTING
Filling the hot water heater
1. Open a hot water tap in the house.
2. Fill the hot water heater through the cold water
connection (XL3).
3. When the water that comes out of the hot water
tap is no longer mixed with air, the water heater is
full and the tap can be closed.
Filling and venting the charge coil
Filling
1. Open the externally mounted filling valve. Fill the
coil in the hot water heater and the rest of the cli-
mate system with water.
2. Open the vent valve (QM22).
3. When the water that exits the vent valve (QM22) is
not mixed with air, close the valve. After a while,
the pressure starts to rise.
4. Close the filling valve when the correct pressure is
obtained.
Venting
1. Vent the coil via the vent valve (QM22) and the rest
of the climate system via the relevant vent valves.
2. Keep topping up and venting until all air has been
removed and the pressure is correct.
The figure shows VPB S200.
